Starlight Rising

Not too long after Starlight was taken in as a friendship student by Twilight, she was ordered to go out and make a friend on her own. She did what Twilight asked of her but this friend turned out to be an old foe of hers, Trixie Lulamoon. At first Twilight tried to stop this friendship but eventually realized that she should give Starlight the same leverage in making her own friends as Celestia did her.

Twilight not only accepted Starlight's friendship with Trixie, she even took Trixie in as a friendship student when Starlight asked her to. It would not take long for Starlight and Trixie to become much more than friends. This was something Twilight did not like and when they became inseparable and intimate, Twilight knew she had to do something to end their relationship so one night she joined Starlight and Trixie in an intimate encounter but that would cause an unexpected result, Trixie fell for Twilight.

It would not be long after Trixie fell in love with Twilight that she lost interest in Starlight and Starlight lost interest in Trixie. With this being the case, Trixie and Twilight decided Starlight must go, so Twilight asked Celestia to invite Starlight up to Canterlot for a few days and sent Spike with her. During their absence, Trixie took full control of Twilight, cast a fertility spell on her and got her pregnant. During Starlight's time in Canterlot, she accepted a position as Celestia's protege and would be relocating to Canterlot permanently.

When they returned to Ponyville so Starlight could get her possessions, Twilight and Trixie decided that Spike must go with Starlight for good and was able to get Celestia to allow that. Now Trixie has complete and absolute control over Twilight while Starlight is beginning her new life as Celestia's protege. While Twilight is falling deeper and deeper into the abyss of Trixie's control, Starlight sees nothing but a bright future, a future in which she could one day become much more than Celestia's protege.
